Dr. Paul R. McHugh, the Distinguished Service Professor of Psychiatry at Johns Hopkins University and former psychiatrist–in-chief for Johns Hopkins Hospital, who has studied sexuality for 40 years, said it is a scientific fact that “there is no gay gene.”

“Environment,” however, “is very important,” said Dr. McHugh, author of The Mind Has Mountains: Reflections on Society and Psychiatry. He also explained that the permissive sexual culture in the United States today has confused “desire” with “love,” and that homosexuality is a false or “erroneous desire.”
